I have a PSE nova, It is at 67lbs and 28 draw length shoots 217 fps. i shoot Easton XX75 2213 at 125 grain. I can shoot great groupings at 15-25 yards, But any farther than that i am all over the place. I am wondering is it my grainage is to heavy or what, should i switch to carbons, or should i get a new bow. If you guys recomend a new bow what kind is a good solid hunting bow that i can use for turkey-moose. Thanks
